CASTING MECHANISM FOR TYPOGRAPHICAL MACHINES.

Specification of Letters Patent.

Patented Dec. 30, 1919.

Original application filed June 10, 191.5, Serial 1%. 33,382. Divided and this application filed November 15,

To all whom it may concern:

Be it known that I, BAYLUS CADE, a citizen of the United States, residing at Shelby, in the county of Cleveland and State of North Carolina, have invented new and use ful Improvements in Casting Mechanism for Typographical Machines, of which the following is a specification.

The present invention relates to improvements in line casting machines and more particularly to those of the class shown and described in my Patent No. 1,257,185, granted February 19, 1918, of which the present is a division.

The primary objects of the invention are to provide an improved casting mechanism which includes vise jaws and alining bars which gather together the selected matrices, aline and clamp them before the mold, and a mold composed of sections which come together endwise before the line of as sembled matrices to form the mold cavity and which after the cast separate and thereby enable the slug to be readily ejected therefrom.

To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.

in tie accompanying drawings Figure 1 is a side elevation of a line composing and casting machine constructed in accordance with the present invention.

Casting mechanism embodying the present invention may be used generally in conjunction with machines of different types for assembling and composing lines of matrices from which slugs are to be cast, although the particular embodiment of the casting mechanism shown herein is especially adapted for use in conjunction with a line composing machine of the class shown and described in my application hcreinbefore referred to. Inasmuch as the present applioation pertains to the casting mechanism only, it is unnecessary to describe in detail herein the matrix assembling mechanism, reference being made to said prior application for a det-aileo illustration and description there of, it being suitlicient to state that the matrices 1 from which the slugs are cast are carried by a set of rotatable sectors 2, that the sectors are set in different positions by matrix selecting mechanism 8 arranged at one side of the periphery of the sectors, and that wh n the desired matrices hav been selected, they will be arranged in a row and are adapted to be moved outwardly radially of the sectors into cooperative relation with the casting mechanism.

lhe casting mechanism in the present i11- stance is mounted on a frame 5 which is supported on the base frame 6 of the machine and in a position substantially diametrically opposite tothe selecting mechanism. The vise and mold, however, are mounted on a bracket 297 which projects rearwardly from the frame 7 which sup ports the matrix sectors and their selecting mechanism. The bracket 29'? supports a rail 298 which extends transversely of the machine, and a pair of slides 299 and 300 are mounted to reciprocate in unison toward and from one another on said rail, the approaching and receding movements of the slides being effectedby a screw 301 which embodies right and left-hand threads engaging the respective slides, the outer end of the screw shaft having a pinion 302 thereon which is connected through the train of gears 303, 304 and 305 to a pinion 306, the latter cooperating with a gear sec tor 307 carried at the outer end of an arm 303. Said arm 308 is pivoted at 309 and carries a roller or projection 310 which cooperates with an operating cam 311, said cam being mounted on a shaft 221 and driven by a pair of cooperating gears 31% and 315, the gear 315 being fiXed to an in termittently revolving shaft 316, the operation of which is controlled in the manner described in my prior application.

The slides 299 and 300 carry a pair of complemental mold sections 32% and 325, the

nold section 325 having a recess 326 which, when the mold sections are brought together, will be opposite to the fiat portion 32f of the mold section 324- and will thus produce a mold cavity in which the slug is cast. The slides 299 and 300 also carry a pair of vise jaws and 323 which are adapted to gather together the selected matrices when they have been brought to a position in front of the casting mechanism and to clamp them in a line of the desired. length. A pair of complemental alining bars and 330 f project from the 1nne1.*.s1des of the vise I jaws, these alining bars entering the aperspending vise jaws 327 and 323.

tures in the bodies of the selected matrices whereupon the approaching movement of the vise is interrupted, the matrix carrying sectors are shifted forwardly, thereby causing the selected matrices to be drawn out a suitable distance from the peripheries of the sectors, and while the latter are in their forward position the approaching movements of the vise jaws are resumed. vi'heroupon the vise aws gather together the line of matrices into a line of the desired length, this being permitted by the flexible stems supporting the matrices. T he final closing movements of the vise jaws cause the alining bars 329 and 330 to produce accurate alinement of the matrices. In order to maintain. the proper relation between the alining bars 329 and 330, they are preferably formed on their cooperating faces with ribs 331 and 332 and corresponding grooves 333 and 334.

The mold sections 324. and 325 are movable laterally with relation to the corre- In the present instance, the mold sections are supported on pins 335 and 336, and springs 337 and .333 operate to normally force the mold sections rearwardly with relation to the vise jaws. The mold section 325 is provided with an ejector for removing the slug therefrom. In the present instance, this ejector is in the form of a sprin plunger 339 which extends through the top of the mold so as to operate to push the slug out of the recess 326: The

ejecting pin or plunger 339 is depressed at the proper time by an arm 34:0 which is fixed to a shaft 311, said shaft being rocked at appropriate intervals by an arm 342 fixed thereto, a link 343, an arm 3 1st to which said link is connected, said arm 344; being pivoted to the frame at .3415, and a link 346 which in turn is reciprocated at proper in tervals by an appropriate part of the machine.

349 designates a' galley to receive the slugs after they have been cast and trimmed. The galley is provided with a reciprocating follower350 for advancin the slugs therein and to provide room to accommodate the incoming slugs which enter the galley endwise through a slot 351 formed in the inner side wall of the galley. The follower is reciprocated by a link 352 which is attached thereto and an arm 353 which is fixed to the ejector shaft 341. The slugs are trimmed by the passage thereof endwise through a trimming knife 354 which, as shown, is three-s1ded and operates to trim the two flat sides and the foot or bottom of the slug. the trimming knife bein in alinement with the slot 351 leading to the galley. T he slugs are successively positioned to enter the trimming knife by a slug receiver 355, and the slu are pushed from this receiver through the trimming knife by a blade 356 which is carriedby or forms a part of the slide 300. The slug receiver is movable from a position to receive the slug from the mold to a position before the trimmin knife. In the construction shown the slug receiver is fixed to a shaft and this shaft is operatively connected to the ejector shaft .3 t1 by the gears 353 and lVhen the mold section has been retracted with a slug contained in the recess 326 therein, the slug receiver is swung upwardly to a position beneath said mold section and the ejector then opto remove the slug from the mold section 325, causing it to drop into the slug receiver. When the slug receiver swings downwardly into the position shown in Figs. 5 and 11, the slug in the receiver is then in alinement with the trimming knife and the blade 356, and movement of the blade 356, which is carried by the slide 300,

lUO

toward the trimming knife causes the slug to pass through the trimming knife and the slug in advance of the one just trimmed is pushed into the galley. In order to bring the mold section into position directly above the slug receiver, a lever 360 is pro vided, it being pivoted at 361 on'a stationary bracket 36-2 and it has a hook 363 at one end to engage the rear side of the mold section 325 while itsopposite end is arranged to be engaged by a projection 364 on the ejector shaft 341 so that rotation of the ejector shaft in a direction toward the e ector 3&0 to eject the slug from the mold section 325 will simultaneously operate the lever 360 in a direction to push the mold section 325 forwardly against the action of its spring 338, thereby bringing this mold section into a' position directly above the slug receiver.

Justification of the line of matrices is effected by pushing upwardly the wedges of the spacers which have been fed into the line at appropriate intervals. The expanding or pushing upwardly of the wedges of the spacers is effected by a vertical wedgeexpanding slide 365 which is mounted to reciprocate vertically in guides 366 mounted on the bracket 297, and this wedge-expanding slide is operated through a link 367 and an arm 368, the latter being fixed on a rock shaft 369. The rock shaft 369 is provided with an acuating arm 370 which is fixed thereto, and the arm 370 is connected by the link 371 to an arm 372, the latter being fulcrumed or pivoted at 373 and is provided with a roller 37% which is adapted to follow an internal cam 375 mounted on the shaft 53. The roller 37% is pressed yieldably toward its cam by a spring 377 which is connected to the rock shaft 369 through the elements 370, 371 and 372 and is of sufficient strength to force the wedges upwardly to effect justification, the cam determining the period at which justification will be effected and serving to retract the wedge expanding slide.

378 designates a metal pot which may be of the type generally used in machines of this class, it having a spout 379, the mouth of which is adapted to engage and close the rear side of the mold, and a plunger 380 serves to eject metal from the pot throu h the spout and into the mold. The plunger is operated by a plunger arm 381 which is pivoted to the pot at 382, a weight 383 being mounted on the arm 381, providing the power required in actuating the plunger. The casting operation is controlled by a lever 384- which is pivoted at 385 to the base 6 and carries a roller 386 which cotiperates with an appropriately shaped cam 387 whereby the weighted arm 381 and the plunger attached thereto will be permitted to drop and to force molten metal into the mold at the moment the mold sections have been closed in front of the line which is clamped between the vise jaws.

ll feans is provided for controlling the operation of the plunger 380 in order to prevent ejection of metal from the pot should an incomplete line of matrices be presented at the casting point. Should the line of matrices be incomplete, then the wedges panding slide 365 would rise to an abnormal degree as the wedge spacers would be unable to fill up or complete the line and the foreing of metal into the mold would cause squirting of the metal through the spaces left between the matrices of the loose or incomplete line. In the construction shown, the shaft 382 to which the plunger actuating arm 381 is connected has a dog 388 fixed thereto and arranged to cooperate with a linger 389, the latter being pivoted to the metal pot at 390 and connected at its lower end by a link 391 to a lever arm 392, the latter being rigidly connected by the shaft 393 to a latch 39-1. This latch has a projection 395 which is adapted to rest upon the periphery of a sector 396, the latter being loosely mounted on the shaft 369 and is movably connected to a second sector 397 by a pin 398 on the latter which works in a slot 399 in the loose sector 396, the sector 397 being fixed on the shaft 369. The projection 395 on the latch ear is wide enough to also rest upon the periphery of the sector 397. The sector 396 is formed with a notch 400 which is adapted to move into a position to receive the projection 395 during the normal stroke of the wedge-expanding slide 365, but should the wedge-expanding slide rise abnormally, the notch 400 will be car ried past the projection 395 and the latch 39% will then be held in elevated position. While the latch is in its elevated posi tion, due to the resting of the projection 395 on the unnotched periphery of either the sector 396 or the sector 397, the finger 389 will occupy a position beneath the free end of the dog 388, and the latter will there by lock the metal ejecting plunger 380 and thus prevent operation thereof, but when the projection 395 rests in the notch 41:00, the finger 389 is clear of the dog 388, as appears in Fig. f, and the plunger 380 is then unlocked and free to operate. The latch 394. is held in cotiperative relation with the sectors 396 and 397 by a spring 401.

After the mold sections have been brought together in front of the line of matrices, the metal pot is moved forwardlv to bring the mouth of the spout thereof against the rear side of the mold, the cast then taking place after which the metal pot recedes preparatorv to the separation of the mold sections. To this end, the metal pot is formed with a base 402 which is slidable in a for ward and rearward direction in horizontal guides 403 formed on the top of the frame 3. A cam 40% is fixed to the shaft 376 and is appropriately shaped to produce the forward and rearward movements of the metal pot, as described. An arm 405 is mounted on the shaft 373, it having a roller 4l06 which follows the groove of the cam 404, and the arm 405 is onerativelv connected to a lever 407, the upper end of the latter being connected to the metal pot.

The shaft 37 6 which carries the cams which control the justification, the movements of the metal not toward and from the mold, the actuation of the plunger which forces the metal into the mold, and the op eration of the rod l? which controls the. relative timing of the operations of the casting mechanism and the matrix selecting mechanism, is driven by a sprocket wheel 4-08 and a cooperating chain 409, the latter beino' operated by appropriate parts oi the machine as desc *ibed by my prior application.
